WR-G69DDCe Receiver Hardware Options

The following factory-fitted hardware options are available for WR-G69DDCe receiver:

External Reference Oscillator Input Option (/XR)

The G69DDCe/XR option includes an additional SMA connector, which can be used to connect an external 10 MHz reference oscillator for the highest possible frequency accuracy. The input is AC coupled and has an internal impedance of 50 ohm. The reference oscillator can be either sine or square wave between -5 dBm to +10 dBm.

Reference Oscillator Output Option (/RO)

The G69DDCe/RO option includes an additional SMA connector, which can be used to output the 10 MHz reference frequency. This is useful for situations where the receiver's internal oscillator is to be used as a reference for other equipment. The output is AC coupled, clipped sine-wave at +5 dBm @ 50 ohm.

One pulse per second (1PPS) input option (/1PPS)

The G69DDCe/1PPS option includes an additional SMA connector, to accept the input from the 1PPS precise timing signal (one pulse per second).

This is useful for the time stamping of received signals and is used in situations where a signal received by multiple separate receivers has to be time synchronized. This is a 50 ohm terminated digital input with a logic threshold of 1.2V. This option is supported in the G69DDC SDK. Only the USB connection is supported.

Low profile radiator (/LP)

The G69DDCe/LP option provides an alternative factory fitted low profile cooling radiator.

This option extends the receiver's operating temperature by ~4 °C and is suited for low profile installations, or wall mounting.


To order a receiver with any of the above options, simply add the option code(s) to the receiver model number. For example, for a receiver with the external reference oscillator option, the model number will be G69DDCe/XR. Options can be mixed together, for example G69DDCe/XR/RO denotes a receiver with both options installed.
